Definitions

  • the present invention generally relates to accessing digital data received from a communications network, and more particularly, to a method and an apparatus for optimizing access to that data.
  • Dedicated devices for accessing digital data services such as Internet Protocol Set Top Boxes for rendering of audiovisual services (e.g. IPTV-STBs) have minimal hardware resources in order to reduce production costs and ensure a competitive market price. In particular, processing and memory resources are tailored to the strictly needed. But with ever enhanced service offers and improved graphical service offering presentation, service portals, that are the entry point to access a service offering, become more and more complex and demanding with relation to the limited resources of the dedicated devices. Service portals typically comprise a hierarchy of menus and pages, comprising not only text, but also voluminous images and scripts that must be executed. All of this information must be downloaded from a remote server in a network before being rendered, which slows down the reaction time of the devices.
  • IPTV-STBs IPTV-STBs
  • the 'best candidate' chosen according to a specific cache management policy is not always the best choice; for example, it is not desirable to remove from cache memory the pages and resources of a main service offering access portal application that functions as an entry point for a user to access a service offer, even if the data related to that main service offering access portal is the 'oldest' data in cache.
  • the present invention aims at alleviating some of the inconveniences of prior art.
  • the invention proposes a solution for cache memory management that avoids among others the aforementioned drawbacks of prior art cache memory management.
  • the invention comprises application of different cache memory management policies according to data origin.

  • the method further comprises a step of exclusion of adding of the data to the cache memory if cache memory fill level is higher than a first cache memory fill level that is lower than a maximum cache memory fill level.
  • the method further comprises a step of, if it is determined that the service offering provider is not in the list of preferred service offering providers and cache memory fill level is under a second cache memory fill level that is lower than the first cache memory fill level, and it is determined that a type of the data is in a list of preferred data types, the list of preferred data types being present in the receiver device, adding of the data to the cache memory.
  • the method further comprises a step of, if the cache memory fill level is under a third fill level that is lower than the second cache memory fill level, adding of the data to the cache memory.
  • the list of preferred data types comprises an image type.
  • the list of preferred data types comprises an executable script type.
  • the determination if the service offering provider from which the data originated is in a list of preferred service offering providers is based on a comparison of a Unified Resource Locator present in the request with the Unified Resource Locators of the preferred service offering providers in the list of preferred service offering providers.
  • the determination if the service offering provider from which the data originated is in a list of preferred service offering providers is based on a comparison of an Internet Protocol address present in the request, indicating an origin of the data, with Internet Protocol addresses of the preferred service offering providers in the list of preferred service offering providers.
  • the invention also concerns a device for management of cache memory, the device comprising a network interface for reception of a request to add data, related to reception of an audiovisual services offering and the data originating from a network to which the device is connected, to the cache memory; and the device further comprising a controller for determining that a service offering provider from which the data originates is in a list of preferred service offering providers, the list being present in the device, and for adding to the cache memory of the data unless adding of data is excluded.

  • the receiver 12 further comprises a cache memory controller 111, a cache memory 112, and a switch 113.
  • Cache memory controller operates switch 113 via connection 1015 in order to provide, via connection 1017, data to display memory 114 either directly received via connection 1011 to network interface 110 from the network 11 or from cache memory 112 when the data was previously received and stored in the cache memory.

  • Specific components that are not shown provide the requests for data that are received by the cache controller 111 via connection 1023.
  • Figure 1 is illustrated with only one service provider and only one receiver device. Of course, the invention is also applicable to an environment where more than one service provider and/or more than one receiver device are used.
  • the data that is stored in cache is part of a service offering presentation application that is downloaded by receiver device 12 from the network 11 and service offering presentation application server.
  • the data that is stored in cache memory are part of web application pages that are part of a service offering access portal giving the user of receiver device 12 access to an offering of audiovisual services.
  • more than one service provider provides an offering of audiovisual services to a receiver device according to the invention.
  • One of these service providers may be considered as being a privileged audiovisual service offering provider after determination that the service provider is present in a list of privileged service offering providers. Then, the invention applies different caching policies according to the audiovisual service offering provider from which the data originates.
  • determination of privileged audiovisual service offering provider is based on an address used to retrieve the data, for example an IP address.
  • determination if an audiovisual service offering provider is in a list of privileged audiovisual service offering providers is based on a comparison of a resource locator used to retrieve the data, such as an URL (Uniform Resource Locator).
  • URL Uniform Resource Locator
  • the URL contains the name of the privileged audiovisual service offering provider, or any other identifier identifying the privileged audiovisual service offering provider.
  • distinction between data to add and not to add is based on the type of service that the data relates to, for example live or Video on Demand type services.
  • the previous variants are combined, which is advantageous in certain situations of use, for example when a user uses his receiver mostly to receive live services from a first audiovisual service offering provider, and to receive Video on Demand services from a second audiovisual service offering provider.
  • this distinction between data that is considered by the receiver as originating from a non-preferred provider and data that is considered originating from a preferred provider is fixed in the receiver by the manufacturer or by the audiovisual service offering provider that sold or hires the receiver as part of a package including a subscription to a service offering.
  • this distinction between what is considered to be originating from a preferred or a non-preferred audiovisual data offering provider is determined by the receiver itself, based on self-analysis of the use of the receiver.
  • the invention comprises a step of exclusion of data originating from a non-preferred audiovisual service offering provider of at least one data type (see fig.3 , zone 311).
  • a non-preferred audiovisual service offering provider of at least one data type see fig.3 , zone 311).
  • This feature allows among others to avoid very fast filling of cache memory with voluminous data. Typically, such a situation occurs when a user is navigating in a VoD service offering presentation application that typically comprises many voluminous images, movie trailers and publicity, possibly accompanied by voluminous executable scripts such as JavaScript.
  • the feature then allows to exclude one or more of these types of data from being stored in cache memory when a certain cache memory fill level threshold is exceeded, and thus keeps space in cache memory to store more 'useful' data.
  • the device implementing the invention can indifferently be connected to a wired network such as the wired network 11 of figure 1 , or to a wireless network (not shown).
  • the wired networks or wireless networks can indifferently be of any type, such as based on Ethernet, WiFi, WiMAX or IEEE 1394 FireWire.
  • the cache memory controller takes into account the amount of data to be stored in the determination if the cache memory fill level exceeds one of the thresholds that are defined according to the invention.
  • Figure 2 shows an alternative embodiment of a receiver device 13 comprising an embodiment of the invention.
  • the receiver device 13 comprises a Central Processing Unit (CPU) 220, a clock 230, a network interface 240, a graphics interface 250, a user interface 260, a Read-Only Memory (ROM) 200 and a Random Access Memory (RAM) 210. All of these components are interconnected via a data-and communication bus 270.
  • CPU 220 controls the device 13 according to a program that is stored in ROM 200 in a memory zone 201.
  • Clock device 230 provides the components of receiver 13 with a common timing in order to sequence and synchronize their operation.
  • Network interface 240 receives and transmits data with external devices via connection 1010.
  • Graphics interface 250 is connected to an external rendering device via connection 1019.
  • User interface 2010 receives input commands from a user via connection 2010.
  • Memory zone 201 comprises also instructions that implement the method of the invention.
  • CPU 220 copies the program 'Prog' from ROM memory zone 201 into memory zone 211 of RAM memory 210, and executes the copied program.
  • the program allocates memory space for variables needed for its execution in memory zone 214, and reserves a memory zone 212 to be used as cache memory.
  • the device 13 is now started and upon reception of a request for audiovisual service application data, the method of the invention is activated.
  • Memory zone 202 of ROM memory 200 comprises addresses of service portal, giving the user of the device 13 access to a last visited access portal for accessing an audiovisual services offering.
  • Memory zone 203 comprises a list of preferred service offering providers,
  • device 13 comprises a specific memory zone for cache memory, which offers faster access than the 'standard' memory 210.
  • CPU 220 of device 13 comprises a specific memory zone for cache memory, which has the advantage of being a specific memory that can directly be accessed by CPU without using data- and communication bus 270 which is shared between the components 230,240,250,260, 200 and 210, thereby offering advantageously fast access.
  • Figure 3 diagrammatically shows progressive exclusion of data adding to cache memory as a function of various parameters such as preferred provider, type of data and cache memory fill level, according to various particular embodiments of the invention.
  • Line 305 represents a maximum cache memory fill level threshold.
  • Line 300 represents zero data in cache memory.
  • 304, 303 and 302 represent respectively first, second and third cache memory fill level thresholds.
  • the cache memory fill level is between the third fill level 302 and a second fill level 303, adding of certain types of data from non-preferred providers is excluded.
  • adding of data from non-preferred providers is excluded.
  • cache memory fill level reaches above the first fill level 304, all data adding is excluded.
  • This last feature is particularly interesting in an application of the invention 'on top of' an existing cache with its existing cache management, and the feature then avoids reaching a full cache and thus avoids triggering the cache's own cache management, and thus avoids high delay times for adding data to cache and avoids loss of control over which data is removed from the cache memory (e.g. existing cache management might very well remove data related to a privileged provider, since it is considered as being 'old data').
  • 'adding' of data is different from 'replacing' or 'updating' or 'refreshing' of data. For example, even if in zone 312 adding of data from non-preferred providers is excluded, replacement of existing data is still allowed. This is for example useful in a situation where obsolete version data is replaced by new version data.
  • Figure 4 shows an algorithm implementing a particular embodiment of the method of the invention, implemented for example by the receiver device of figure 1 , or by the receiver device of figure 2 .
  • variables and attributes are initialized that are used by the algorithm. These variables are for example stored in memory zone 214 of device 13 of figure 2 , or in registers of memory controller 111 of figure 1 .
  • a request for adding of data to cache memory is received. This request is for example received by cache memory controller 111 of device 12 of figure 1 via connection 1023, or by CPU 220 of device 13 figure 2 via communication bus 270.
  • the origin of this request is for example a user initiated action while the user is navigating in a service offering presentation portal that gives the user access to audiovisual services.
  • step 403 it is determined if the service provider from which the data originates is in a list of preferred service offering providers, said list being for example present in ROM memory zone 203 of device 13. If it is determined in step 403 that the service provider from which the data originates is in a list of preferred service offering providers, the data is added to the cache memory unless adding to cache memory of data is excluded, where after the algorithm proceeds with step 307. On the affirmative, the algorithm proceeds with step 405 of adding of data unless adding of data is excluded. If however it is determined in step 403 that the service provider from which the data originates is NOT in the list of preferred service offering providers, the data is not added, and the algorithm proceeds with step 401 of awaiting a reception of a data add request.
  • the determination steps of exceeding of cache fill level with regard to the different thresholds according to the different variants of the invention are for example done by cache controller 111 of figure 1 that determines the cache fill level of cache memory 111 via connection 1021, or with reference to figure 2 , by CPU 220 that determines the fill level of cache memory zone 212 via signals exchanged on data- and communication bus 270.
  • the different thresholds, maximum cache memory fill level and cache memory size are predetermined by the receiver device manufacturer and stored in a nonvolatile memory zone of the receiver device, e.g. in ROM memory 200 of device 13 of figure 2 .
  • the thresholds, maximum cache memory fill level and cache memory size are specified as an absolute value (e.g. the first threshold is specified as 7.9 Mbyte, the maximum cache memory fill level is specified as 9.9 Mbyte) or, according to a different variant, the different thresholds and maximum cache memory fill level are specified as a relative value related to the cache memory size (i.e. the first threshold is specified as being 79% of cache memory size).
  • the different thresholds and optionally cache memory size are alterable by a remote configuration device, for example by a configuration server of a service offering provider, through a remote configuration protocol such as SNMP (Simple Network Management Protocol) or TR-069 (Technical Report 069).

  • TR-069 Technical Report 069
  • the service offering provider can remotely tailor the size of the cache memory to the size of the data corresponding for example to the added size of all data related to the audiovisual service offering presentation application (also called access portal), so that the cache memory is of sufficient size to contain all of the data of that application and the receiver device never has to download twice the same data since it is sure to be stored in cache memory, i.e.
  • the service offering provider updates the access portal, it can adapt the cache memory size to the total size of the updated access portal by transmitting a dedicated configuration command to the receiver device.
  • the thresholds maximum cache memory fill level and cache memory size are determined according to a rule of thumb.
  • cache memory size is fixed to a value allowing to contain at maximum one hundred web pages of typical size
  • the first threshold is fixed to 69 percent of cache memory size
  • each subsequent threshold adds 10 percent to the value fixed for the first threshold, thus 79 percent of maximum cache memory size for the second threshold, 89 percent of cache memory size for the fourth threshold, and 99 percent of cache memory size for the fourth threshold.
  • the thresholds and possibly the cache memory size are tailored to the type and size of data to be stored in cache memory. For example, if the cache memory should be able to store VoD trailers, the cache memory size is relatively large, and the thresholds are spaced in such a manner that the cache memory space between two subsequent thresholds is sufficient to hold at least several items of a specific data type, such as Video on Demand images. According to a variant embodiment, various data types of data from non-privileged providers influence differently on the cache memory policy.
